Salt helps preserve distillers

High-moisture distillers grains can be successfully stored in bunker silos in the summer, according to Illinois State University research.

After 113 days of storage from May to August, the nutrient content of wet distillers grains topped with granular salt and covered with a white plastic silo cover was no different than its nutrient content going into storage. There also was “little change” in the color of the distillers after 113 days in storage, say the researchers.

The researchers also successfully stored wet distillers using a limestone crust, but found that the salt covering method was more effective.

The study was presented in March at the American Dairy Science Association’s Midwestern sectional meeting in Des Moines, Iowa.
